VS 2010 Creating And Removing Controls?
Sep 2, 2010I'm making quite the complex program, and while I try to figure out some more advanced methods that work better for what I'm trying to do, I'd like to learn how to do this (which is a bit of a roundabout method to what I've been trying). I'm wondering, how can I programatically create and remove objects? For example, I have webbrowser1. I want to remove it and create another webbrowser that I will also name webbrowser1. (therefore, the instance of the original must be removed)

VS 2010 Removing Some Controls From The Controlscollection?
Oct 17, 2011I have a problem with a bit of code that is supposed to delete every controls on a form appart from the 2 first controls
vb2010
Private Sub ClearCheck(ByRef Container As Control)
Dim ctl As Control
Dim Boxtype As Control
Dim i As UShort = 0
[Code]...
The behavior is strange, I can't find any logic to it, it will sometime delete a part of the objects, other times it will delete other part of the objects. If I run it more than once, I can achieve the wanted result and remove all controls except the 2 I want to keep. It's as if it was checking 1 out of 2 controls.
To give you a better idea I have a combobox on the form and depending on choice it adds appropriate controls (not show/visible true) and add a second combobox to refine the search. If I change the value in the first combobox I want to remove the added controls from the previous combobox.SelectedIndexChanged as well as any control created by the following combobox from the form.
If need be I'll post the code that creates those new controls, but it's quite long so I didn't include it in this post

VS 2010 - Removing Temp Document Stored In Array?
Nov 28, 2011In my desktop, I have folder containing some word document files. I want the filenames of the documents in that folder. So, I used:
Dim strFiles() As String = IO.Directory.GetFiles("X:Documents and SettingsXXXDesktopvvvvv", "*.doc")
All filenames are stored in that array. But it would also include the temp document that Word generates. I am somewhat confused on how to remove this from array. I only need full filenames of the actual documents, which excludes the temp document.

Removing Dynamic Controls ?
Mar 16, 2012I'm having problems removing dynamic controls.
Here is what I'm using:
CODE:
The first sub is for adding the (custom)control, the second sub is for removing the control.
The custom control is a picturebox with a checkbox in the upper-left hand corner, no big deal.
The problem is that when I click the delete command, it only deletes one ckPicture at a time, and allways the last one in the list. I'm also assuming it's doing the same thing in the list(of images). What should I do differently so that it will remove all controls that are checked?
I forgot to add the variables in my namespace.

Removing Form Controls By Name?
Feb 5, 2010This is my first post here as I am in the process of writing my first vb program. I just recently learned VBA and prior to that I had no programming experience. I decided that my first attempt with VB would be to convert a program that I previously wrote in VBA. It runs in an excel workbook but it doesn't actually use any excel functions so I figured it would be acceptable to convert. I am having an issue with removing controls on a userform. A commandbutton adds a line of about 6 controls. The user can add as many lines as they need to input their data. One of the 6 controls is a delete button that deletes the line of controls next to it. I have created a collection named Cashflows that holds each line of controls and each line of controls is named with a number that indexes the name to the line that it appears on in the form. In VBA I use that number to delete the actual controls from the userform and reposition and rename the remaining lines of controls.
Private Sub Delete_Click()
Commandbutton3sub(CInt(Right(Delete.Name, Len(Delete.Name) - 6)))
End Sub

View 2 RepliesRemoving Element From Array?
Oct 11, 2009I haven't used vb.net in about a year. I have a few arrays, the first holds a list of names. that list is used to load files into memory and then based off that file, another array is filled with my custom data type.
array of names is a file. it is not in memory unless it is being written to or read from. the second array is where all of my data is stored Dim fs As New FileStream("EmpVec.vec", FileMode.OpenOrCreate)'EmpVec.vec" is the file that stores all of the names Dim reader As New StreamReader(fs)while not(reader.EndOfStream)'code that is used to load and fill my array'it sees the name, searches for a file with the same name, then loads data from that file into my vector and memory'as i do this, i fill a list box with the name, and another string object (name & vbtab & string)end while. so that is when i populate my arrays what i would like figuring out is how to remove objects from my arrays here is what i got Dim index As Integer = Me.lstEmpList.SelectedIndex EmpVec(index) = Nothing 'EmpVec is the array that stores all of my custom data types
Me.lstEmpList.Items.RemoveAt(index)''this will remove the data from the array but I also save all the contents in the array to the EmpVec File'so when it hits the empty element, it crashes because there is no data'i would basically like to resize it

Creating Dynamic Control Array In VB 2010
Oct 31, 2011I need to dynamically create some sort of 'table' on my form. It should look like:
PIC1 INTEGER1 TIME1
PIC2 INTEGER2 TIME2
PIC3 INTEGER3 TIME3
On top of that it should look like a table and have gridlines between the 'cells' containing the picture/data, which makes it even more difficult for me. Before, control arrays were quite simple in VB6, but I've been searching for 1,5 hours now and I can't figure out how to do this in VB.NET 2010. Any idea how to tackle this the most efficiently?
Removing A Listbox Item When It Stored In An Array?
Jan 7, 2011Basically, the user can type in a name and a job description into two different txt boxes and then click add. It then adds the name to the listbox and stores it in a string list (Public strList As New List(Of String)) it also stores the job description in a string list as well (Public strListDescription As New List(Of String))Then when you select an item in the list box it knows what data to bring up in the txt boxes using an array with these lists:
Code:
Private Sub lstMyCourt_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstMyCourt.SelectedIndexChanged
Dim i As Integer
